What does Water do for you?

This is an enormous question. We’ll cover some of the main points–

Water keeps your cells rigid. Without the cytoplasm inside each cell pushing out against the cell wall, the cells would collapse.

Since your blood, spinal fluid, digestive fluids, et cetera are composed almost entirely of water, without adequate hydration, there’s no way to transport oxygen and nutrients to every cell of the body. There’s also no medium in which to send chemical messages from one part of the nervous system to another.

Water flushes toxins. Throughout the day, the kidneys are constantly and continuously filtering waste products from the blood, and the only way to remove the build-up is by having waste water flushed through, carrying the toxins out of the body. No water means a toxic backup into the blood, kidney failure, and death.

Water is a heat transfer. Whenever you exhale, water vapor is expelled from the lungs, and with it is carried waste heat from the body. In much the same way a dog cools itself by panting, evaporating water from its tongue, so too do we expel waste heat in the warm, moist air or our breath.

Sweat. This one is kind of obvious, but most people don’t realize that we sweat almost constantly throughout the day to vent waste heat whether we feel damp or not. No sweat means overheating means dead brain cells means death.

Sooo…drink your water, kids.
